描述 Description

The DEI5097 line driver is a CMOS integrated circuit designed to directly drive the ARINC 429 avionics’ serial digital data bus. The internal lightning protection circuitry allows compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) without any external components. The device converts TTL/CMOS serial input data to the tri-level RZ bipolar differential modulation format of the ARINC bus. A TTL/CMOS control input selects the output slew rate for HI (100KBS) and LOW (12.5KBS) speed operation. No external timing capacitors are required.
